About Methylpyrrolidone

NMP is massive in the battery industry-a vital solvent used for dissolving binders like PVDF during cathode slurry mixing. However, because it is entirely evaporated out during the drying process and does not remain a component of the physical final battery, it is traditionally filed under processing solvents rather th...
